Abstract

The Syrphidae in the “Guido Grandi Collection” - held in DiSTA, Alma Mater Studiorum University of Bologna – are revised. 3439 specimens and 243 are present in the collection, which includes an interesting donation made by the Italian ento- mologist Mario Bezzi. Merodon unicolor Strobl is recorded for the first time in Italy and other interesting or rare species are dis- cussed. Several records in the collection improved our knowledge of the fauna of Eastern Po Valley and Emilia Romagna Apen- nines. The Syrphid fauna of these two areas is revised and a detailed regional list provided. Knowledge of the Po Valley fauna seems to be fairly complete and well described, thanks to a strong research effort in the last few years. On the other hand, knowl- edge of the syrphid fauna from the Northern Apennines appears to be incomplete, and hence we need to extend monitoring and recording there. Despite this the present lists seem to be sufficiently detailed to be used for practical purposes, including detailed application of the expertise system Syrph the Net in the Emilia Romagna region.

Platycheirus occultus Goeldin de Tiefenau, Maibach et Speight is a wetland species; in the southern part of its distribution it is associated with Phragmites plants (Speight, 2008b). Previously known only from Apenni- nes, the present record is the first for the Po Valley. Sphegina elegans Schummel is the first record for central Italy; the species is currently known from all of Europe, with the Caucasus and European Russia as its eastern limit. Thanks to many recent researches, the eastern part of the Po Valley can be considered as one of the areas in Italy where most is known about the Syrphidae fauna, mostly already published (Daccordi, 1979; Daccordi and Marogna, 1989, Burgio, 1991; Burgio et al., 1997; Birtele et al., 2002; Burgio and Sommaggio, 2002, 2007; Sommaggio and Corazza, 2006).
